I can only comment, mostly, although I do survey elites in Canada and the United States as well. The likely success of Canadian petitions rises as an issue becomes a bigger-picture item. If they see things as simply condominium issues from the complaining, hectoring aunt up north, then, yes, they'll be polite. But if you can come up with a bigger picture that frames these issues in terms of energy self-sufficiency, climate change, long-term goals, negotiating to a post-carbon economy, and dealing with the security and borders issues, then I think you have a nice big-picture North American project that would grab the interest of the public in both Canada and the United States and I dare say probably Mexico as well.
